The proportion of left-handed people in the general population is about 0.10. To simulate this population, we constructed a collection in which p = 0.10. We then conducted four simulations, drawing random samples of different sizes from this collection. Here you see the resulting sampling distributions and corresponding summary tables: Measures from Sample of Collection 1 Measures from Sample of Colection 1 N=200 0.100095 proportion_lefthanded 0.0221608 1005 S1 = mean) S2 = stdDev> S3 = count) Measures from Sample of...

In a survey of 300 people, approximately 15% of the people identified themselves as being left-handed. What are the mean, standard deviation, and shape of the distribution of thesample proportion p-hat of respondents who say they are left-handed? (3 points) Using the normal approximation without the continuity correction, sketch theprobability distribution curve for the distribution of p-hat. Shade equal areas onboth sides of the mean to show an area that represents a probability of .95,and label the upper and lower...

Try to get a population proportion for left-handed people. I'll use presidents of U.S. for my sample. There were 8 presidents that were left-handed, and we've had 45 total presidents. If you can do it, find the 90% confidence interval, and the 80% confidence interval. Compare your lower limits to the real estimated value that 10% of the population is left-handed.

OD Suppose that 12% of the population of the U.S. is left-handed. If a random sample of 130 people from the U.S. is chosen, approximate the probability that at most 14 are left-handed. Use the normal approximation to the binomial with a correction for continuity. Round your answer to at least three decimal places. Do not round any intermediate steps. (If necessary, consult a list of formulas.)
